AS1851-2012 Tank Inspection Requirements in Australia

Fire protection water tank labelled and maintained under AS1851-2012

AS1851-2012 is the Australian Standard that governs the routine service of fire protection systems and equipment, including the inspection and maintenance of water storage tanks used for fire suppression. For property owners, facility managers, and commercial operators, understanding and complying with this standard is essential to ensuring fire system readiness and legal compliance.

What Is AS1851-2012?

AS1851-2012 outlines the procedures for the regular inspection, testing, and maintenance of fire protection systems — including hydrants, fire hose reels, and dedicated water tanks. This standard ensures that all fire safety equipment is operational, structurally sound, and fit for emergency use.

For tanks, the standard defines the frequency and scope of inspections, testing, and recordkeeping.

Why Water Tank Inspections Matter

Water storage tanks that support fire protection systems must be regularly checked for:

  • Leaks or structural deterioration.
  • Corrosion or sediment build-up.
  • Overflow and outlet function.
  • Internal lining integrity.
  • Access hatch condition and signage.

Failure to inspect tanks in accordance with AS1851-2012 can lead to system failure during an emergency and result in non-compliance with building codes or insurance requirements.

According to the standard, tank inspections should follow this general framework:

  • Monthly: Basic external inspection and visual leak checks.
  • Six-monthly: Inspection of inlets, outlets, overflows, and water levels.
  • Annually: Full internal inspection, structural assessment, and water quality check.
  • Five-yearly: Detailed internal inspection (may require draining), cleaning, and structural integrity review.

Qualified personnel must document all inspections, with service records retained for auditing and compliance.
